[texts]THERMAL DECOMPOSITION OF CALCIUM SUPEROXIDE - TSENTSIPER, A. B.
A STUDY HAS BEEN MADE OF THE KINETICS OF DECOMPOSITION OF CALCIUM SUPEROXIDE PREPARED BY VACUUM DECOMPOSITION OF THE COMPOUND CAO2.2H2O2. AN ACTIVATION ENERGY FOR THE PROCESS EQUAL TO 44 KCAL/MOLE HAS BEEN FOUND. MOREOVER, THERE IS INITIALLY A RISE IN THE SUPEROXIDE/PEROXIDE RATIO (SAMPLES OF THE SUPEROXIDE ARE NEVER PURE, AND USUALLY CONTAIN 50% OR LESS OF THE SUPEROXIDE); THIS RISE IS ATTRIBUTED TO A CONTINUATION OF THE SAME TYPE OF REACTION AS THAT INVOLVED IN THE INITIAL PREPARATION, A FURTH...

[texts]PERTURBATION OF A NEARLY-CIRCULAR ORBIT - TIMOSHKOVA, Y. I.
THE SATELLITE MOTION IN A GRAVITATIONAL FIELD OF A NONSPHERICAL ROTATING PLANET IS CONSIDERED. THE MOTION IN THE FIELD OF TWO FIXED CENTERS IS TAKEN AS THE UNPERTURBED ONE. THE LAGRANGE-TYPE EQUATIONS ARE DERIVED FOR THE PERTURBED ELEMENTS OF THE INTERMEDIATE NEARLY-CIRCULAR ORBIT. THE INTEGRATION OF THESE EQUATIONS IS FULFILLED AND THE EXPRESSIONS ARE GIVEN FOR THE CALCULATION OF THE SECULAR, LONG-PERIOD AND SHORT-PERIOD PERTURBATIONS CAUSED BY AN ARBITRARY HARMONICS OF THE PLANET'S POTENTIAL.

[texts]Asymmetry Effects in Numerical Simulation of Supersonic Flows with Upstream Separated Regions - Rodriguez, C. G
The present paper studies the numerical simulation of flows with shock/boundary-layer upstream interaction, under conditions of symmetry in geometry, boundary conditions, and grid. For this purpose, a series of two- and three-dimensional numerical test-cases were carried out. The tests showed that standard numerical schemes, which appear to be symmetry-preserving under most flow configurations, produce nonsymmetric perturbations when large separated regions are present...

[texts]NUMERICAL INVESTIGATION OF VORTEX SHEETS ISSUING FROM A SEPARATION LINE NEAR THE LEADING EDGE - REHBACH, C
THE FORMATION OF A VORTEX SHEET ALONG A LINE NEAR THE LEADING EDGE OF SLENDER DELTA WINGS IS ANALYZED. AN ITERATIVE CALCULATION METHOD IS PROPOSED WHICH IS BASED ON THE SUBSTITUTION OF THE VORTEX SHEET REPRESENTING THE WING AND ITS TRAILING SHEET BY A NETWORK OF CONCENTRATED LINE VORTICES. THE METHOD IS LIMITED TO PLANE DELTA WINGS. RESULTS OF THE NUMERICAL METHOD ARE COMPARED WITH DATA OBTAINED IN A WATER TUNNEL.

[texts]Decay of far flow field in trailing vortices - Baldwin, B. S.
A finite difference machine code is used in the wake vortex problems in the quasi-cylindrical boundary layer approximation. A turbulent energy model containing new features is developed that accounts for the major effects disclosed by more advanced models in which the parameters are not yet established. Several puzzles that arose in previous theoretical investigations of wake vortices are resolved.

[texts]Teaching audience analysis to the technical student - Debs, M. B.
Teaching audience analysis, as practiced in a technical writing course for engineering students, is discussed. Audience analysis is described as the task of defining the audience for a particular piece of writing and determining those characteristics of the audience which constrain the writer and effect reception of the message. A mature technical writing style that shows the tension produced when a text is written to be read and understood is considered in terms of audience analysis...

[texts]Learning from Automation Surprises and ''Going Sour'' Accidents: Progress on Human-Centered Automation - Woods, David D.
Advances in technology and new levels of automation on commercial jet transports has had many effects. There have been positive effects from both an economic and a safety point of view. The technology changes on the flight deck also have had reverberating effects on many other aspects of the aviation system and different aspects of human performance. Operational experience, research investigations, incidents, and occasionally accidents have shown that new and sometimes surprising problems have a...

[texts]Reliable communication in the presence of failures - Birman, Kenneth P.
The design and correctness of a communication facility for a distributed computer system are reported on. The facility provides support for fault-tolerant process groups in the form of a family of reliable multicast protocols that can be used in both local- and wide-area networks. These protocols attain high levels of concurrency, while respecting application-specific delivery ordering constraints, and have varying cost and performance that depend on the degree of ordering desired...

[texts]Construction and demonstration of a 9-string 6 DOF force reflecting joystick for telerobotics - Lindemann, Randel
Confrontation with difficult manipulation tasks in hostile environments such as space, has led to the development of means to transport the human's senses, skills and cognition to the remote site. The use of advanced Telerobotics to achieve this goal is examined. A novel and universal hand controller based on a fully parallel mechanical architecture is discussed. The design and implementation of this 6 DOF force reflecting joystick is shown in relationship to the general philosophy of achieving ...

[texts]Experimental and analytical studies of a true airspeed sensor - Goglia, G. L.
A true airspeed sensor based on the precession of a vortex whistle for sensing airspeeds up to 321.9 km/hr (200 mph). In an attempt to model the complicated fluid mechanics of the vortex precession, three dimensional, inviscid, unsteady, incompressible fluid flow was studied by using the hydrodynamical linearized stability theory. The temporal stability approach was used to derive the relationship between the true airspeed and frequency response...

[texts]Renal-Stone Risk Assessment During Space Shuttle Flights - Whitson, Peggy A.
The metabolic and environmental factors influencing renal stone formation before, during, and after Space Shuttle flights were assessed. We established the contributing roles of dietary factors in relationship to the urinary risk factors associated with renal stone formation. 24-hr urine samples were collected prior to, during space flight, and following landing. Urinary factors associated with renal stone formation were analyzed and the relative urinary supersaturation ratios of calcium oxalate...

[texts]Formation of Lignans(-)-Secoisolariciresinol and (-)-Matairesinol with Forsythia intermedia Cell-Free Extracts - Umezawa, Toshiaki
In vivo labeling experiments of Forsythia intermedia plant tissue with [8-(C-14)]- and [9,9-(2)H2,OC(2)H3]coniferyl alcohols revealed that the lignans, (-)-secoisolariciresinol and (-)-matairesinol, were derived from two coniferyl alcohol molecules; no evidence for the formation of the corresponding ()-enantiomers was found. Administration of (/-)-[Ar-(H-3)] secoisolariciresinols to excised shoots of F.intermedia resulted in a significant conversion into (-)-matairesinol; again, the ()-antipode ...

[texts]Instability and Transition of Flow at, and Near, an Attachment-Line: Including Control by Surface Suction - Smith, A.
Experiments have been performed on an untapered, swept cylinder model in the Cranfield College of Aeronautics 8 ft x 6 ft low-speed wind tunnel to investigate the effect of surface transpiration on the process of relaminarization in the attachment-line boundary layer. Suction coefficients for complete suppression of turbulence were determined as a function of Reynolds number and spanwise distance. The effect of attachment-line suction on the spanwise propagation of gross disturbances emanating f...
